The T-65 plumbing T-Drill is a heavy-duty, portable drill that makes plumbers quite happy. Its purpose is to make holes or cuts and make T-joints in pipes in materials like stainless steel and copper. What’s great about this tool is that you don’t need to buy any additional T pieces – it has everything that you need.
The T-65 and all other T-drills operate on the same principle. First, it makes a whole in the main tube, the drill’s head expands inside the whole and drills backwards. This movement creates an outwards opening and eventually makes a T-shape.
The plumber then inserts a pipe in the newly created hole and makes a strong T-attachment with the appropriate sealant. Check it out!
